Abstract
The invention discloses a pedal mechanism with double overrunning clutches. The pedal mechanism is used for driving a bicycle and comprises a spindle, a large chain wheel, a small chain wheel, a pair of pedal devices and the overrunning clutches. The large chain wheel is arranged on the spindle in a sleeving mode. The axis of the small chain wheel is parallel to that of the large chain wheel. Each pedal device comprises a connection rod and a pedal. The connection rods are arranged on the spindle in a sleeving mode. The pedals drive the connection rods to swing in a fan-shaped reciprocating mode. The overrunning clutches are connected with the connection rods and connected with the large chain wheel or the spindle. According to the pedal mechanism, when the pedals drive the connection rods to swing in the fan-shaped reciprocating mode, the connection rods drive the large chain wheel to rotate after driving the spindle to rotate through the overrunning clutches, or the connection rods drive the large chain wheel to rotate directly through the overrunning clutches, and the overrunning clutches make the large chain wheel always rotate in the same direction. Compared with the prior art, a most effective segment of straight line in an arc is used for fan-shaped reciprocating swinging, the efficiency is high, riding effort is saved, circumferential rotation is not needed, and the occupied space is small. Meanwhile, each pedal can be independently trodden for driving, and the pedals can be trodden for driving simultaneously, and alternate treading is not needed, so that higher convenience is achieved.
